Description

Technical Field

[0001] This utility model relates to the field of metal threaded connectors, and in particular to a device for preventing loosening and reinforcing metal threaded connectors. Background Technology

[0002] Threaded metal fasteners are the most common connection method in mechanical structures, relying on the friction of the threaded pair to achieve fastening.

[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: when existing metal threaded connectors are used for a long time or subjected to external forces such as vibration and impact, the nuts are prone to loosening or even falling off, which not only affects the normal operation of the equipment, but may also cause safety accidents. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that existing metal threaded connectors are prone to nut loosening or even falling off when used for a long time or subjected to external forces such as vibration and impact. This will affect the normal operation of the equipment and may also cause safety accidents. To this end, we propose a strengthening device for preventing loosening of metal threaded connectors.

[0005] To achieve the above objectives, this application adopts the following technical solution: a reinforcing device for preventing loosening of a metal threaded connector, comprising a threaded connecting rod body, a nut threadedly connected to the surface of the threaded connecting rod body, insertion holes on both sides of the threaded connecting rod body, through holes on both sides of the inner cavity of the nut, sleeves fixedly connected to both sides of the nut, an insertion rod slidably connected inside the sleeve, a first locking groove and a second locking groove on both ends of the sleeve, slots on both ends of the insertion rod, a storage spring fixedly connected inside the slot, and a locking block fixedly connected to one end of the storage spring.

[0006] Preferably, the external shape of the snap-fit ​​block matches the internal shape of the first snap-fit ​​groove and the second snap-fit ​​groove, the surface of the plug rod is slidably connected to the inside of the plug hole, and the outer diameter of the plug rod is adapted to the inner diameter of the plug hole.

[0007] Preferably, sliding grooves are provided on both sides of the inner cavity of the slot, and sliders are fixedly connected to both sides of the plug rod.

[0008] Preferably, a handle is fixedly connected to one side of the plug rod.

[0009] Preferably, a gasket is slidably connected to the surface of the threaded connecting rod body, and the top and bottom of the gasket are provided with anti-slip textures.

[0010] Preferably, the top and bottom of the sleeve cavity are provided with limit grooves, and the top and bottom of the insertion rod are fixedly connected with limit blocks.

[0011] The technical effects and advantages of this utility model are as follows: In this invention, after rotating the nut to a predetermined position on the threaded connecting rod body, the handles on both sides of the sleeve are pushed, causing the insertion rod to slide along the inside of the sleeve. When the insertion rod passes through the insertion hole of the nut and enters the insertion hole of the threaded connecting rod body, the locking block can be pressed to cause the energy storage spring to retract into the groove and disengage from the inside of the first locking groove. Subsequently, by moving the insertion rod to insert it into the insertion hole, the locking block is locked into the inside of the second locking groove by the reset action of the energy storage spring, thereby fixing the insertion rod, preventing the nut from loosening on the threaded connecting rod body, and improving the stability of the threaded connector under vibration or external force.

[0014] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0015] Reference Figure 1 - Figure 4As shown, this utility model provides a technical solution: a metal threaded connector anti-loosening reinforcement device, including a threaded connecting rod body 1, a nut 2 threadedly connected to the surface of the threaded connecting rod body 1, insertion holes 3 on both sides of the threaded connecting rod body 1, through holes 4 on both sides of the inner cavity of the nut 2, sleeves 5 fixedly connected to both sides of the nut 2, an insertion rod 18 slidably connected inside the sleeve 5, a first snap-fit ​​groove 6 and a second snap-fit ​​groove 7 on both ends of the sleeve 5, slots 8 on both ends of the insertion rod 18, a storage spring 9 fixedly connected inside the slot 8, a snap-fit ​​block 10 fixedly connected to one end of the storage spring 9, and a handle 17 fixedly connected to one side of the insertion rod 18; Specifically: After rotating the nut 2 to the predetermined position of the threaded connecting rod body 1, push the handles 17 on both sides of the sleeve 5 to make the insertion rod 18 slide along the inside of the sleeve 5. When the insertion rod 18 passes through the insertion hole 4 of the nut 2 and enters the insertion hole 3 of the threaded connecting rod body 1, the locking block 10 can be pressed to cause the energy storage spring 9 to retract into the groove 8 and disengage from the inside of the first locking groove 6. Then, by moving the insertion rod 18 to insert it into the inside of the insertion hole 3, the locking block 10 is locked into the inside of the second locking groove 7 by the reset action of the energy storage spring 9, thereby fixing the insertion rod 18, preventing the nut 2 from loosening on the threaded connecting rod body 1, and improving the stability of the threaded connection when subjected to vibration or external force.

[0016] Reference Figure 4 As shown, in this embodiment: the external shape of the snap-fit ​​block 10 matches the internal shape of the first snap-fit ​​groove 6 and the second snap-fit ​​groove 7, the surface of the plug-in rod 18 is slidably connected to the inside of the plug-in hole 3, and the outer diameter of the plug-in rod 18 is adapted to the inner diameter of the plug-in hole 3. Specifically, this design allows the locking block 10 to be precisely and securely embedded in the first locking groove 6 and the second locking groove 7, ensuring that the locking block 10 can reliably engage after the insertion rod 18 moves to the corresponding position, thus providing a good fixing effect. The surface of the insertion rod 18 slides in connection with the inside of the insertion hole 3, and the outer diameter of the insertion rod 18 matches the inner diameter of the insertion hole 3, ensuring that the insertion rod 18 can slide smoothly in the insertion hole 3. It will not wobble due to excessive gap, affecting the stability of the fixation, nor will it be difficult to slide due to insufficient gap, affecting the convenience of operation. Through these precise structural designs and adaptations, the reliability and practicality of the entire anti-loosening reinforcement device for metal threaded connectors are greatly improved.

[0017] Reference Figure 4 As shown in this embodiment: sliding grooves 11 are provided on both sides of the inner cavity of the slot 8, and sliders 12 are fixedly connected to both sides of the plug rod 18. Specifically, this structural design allows the sliders 12 on both sides of the plug rod 18 to slide smoothly along the slide groove 11 when the plug rod 18 moves within the slot 8. The slide groove 11 provides a clear sliding trajectory for the sliders 12, ensuring that the plug rod 18 will not deviate during movement, thus guaranteeing the accuracy and stability of the plug rod 18's movement.

[0018] Reference Figure 1 As shown in this embodiment: a gasket 15 is slidably connected to the surface of the threaded connecting rod body 1, and anti-slip textures 16 are provided on the top and bottom of the gasket 15; Specifically, the anti-slip texture 16 design on the gasket 15 can effectively increase the friction between the gasket 15 and the contact surface. When the metal threaded connector is subjected to external force, the anti-slip texture 16 can prevent the gasket 15 from sliding relative to each other, thereby avoiding the loosening of the threaded connection caused by the movement of the gasket 15.

[0019] Reference Figure 4 As shown in this embodiment: the top and bottom of the inner cavity of the sleeve 5 are provided with limiting grooves 13, and the top and bottom of the insertion rod 18 are fixedly connected with limiting blocks 14; Specifically, the cooperation between the limiting groove 13 and the limiting block 14 provides further constraint on the movement of the plug rod 18 within the sleeve 5. When the plug rod 18 moves within the sleeve 5, the limiting block 14 will slide stably along the trajectory of the limiting groove 13.

[0020] Working principle: After rotating the nut 2 to the predetermined position of the threaded connecting rod body 1, push the handles 17 on both sides of the sleeve 5 to make the insertion rod 18 slide along the inside of the sleeve 5. When the insertion rod 18 passes through the insertion hole 4 of the nut 2 and enters the insertion hole 3 of the threaded connecting rod body 1, the locking block 10 can be pressed to cause the energy storage spring 9 to retract into the groove 8 and disengage from the inside of the first locking groove 6. Then, by moving the insertion rod 18 to insert it into the inside of the insertion hole 3, the locking block 10 is locked into the inside of the second locking groove 7 by the reset action of the energy storage spring 9, thereby fixing the insertion rod 18, preventing the nut 2 from loosening on the threaded connecting rod body 1, and improving the stability of the threaded connection when subjected to vibration or external force.

[0021] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
